Use explicit variable and function names to make the code easy to understand.
Avoid duplicating code as much as possible by using functions and classes.
Write comments to explain complex parts of the code, but do not overload the code with unnecessary comments.
Use code analysis tools to detect errors and quality problems.
Write unit tests to ensure that the code works properly and to facilitate maintenance in the future.
Use consistent coding conventions to improve readability.
Avoid overly long functions by breaking them down into smaller, easier to understand functions.
Use constants for values that do not change to avoid input errors and to facilitate maintenance.
Avoid unnecessary external dependencies by using well-tested and widely used libraries and frameworks.
Always think about long-term maintainability and scalability when writing code, even if it takes a little longer at first.
